RAIL-FASTENING.

Specification of Letters Patent.

Application tiled May 16, 1911.

Patented Feb. 13, 1912.

serial No. 627,410.

To all whom it may concern:

.Be it known that I, BENJAMIN MGCANN, a citizen of the United States,residing at Moundsville, in the county of Marshall and State of I/VestVirginia, have invented new and useful Improvements in Rail-Fastenings,of which the following is a specification.v

This invention relates to rail fastenings and particularly to a fastenerwhich is constructed for use upon metal ties, and has for an object toprovide a fastening which will include an eXpansible member of wood anda metal retaining spike, the latter being adapted to be driven into theformer and to expand the same against the walls of its receiving openingin the tie.

In the drawing, forming a portion of this specification and in whichlike numerals of reference indicate similar parts in the several views:Figure 1 is a plan view of a portion of a track structure showing myimproved rail fastening device applied with the supporting tie. Fig. 2is a plan view of the tie. Fig. 3 is a section therethrough on line 3 3of Fig. 2. Fig. 4 is a view similar to Fig. 3 showing a slightlymodified form of fastening. Fig. 5 is a similar view showing anothermodified form of fastening. Fig. 6 is a similar view of a still furthermodified form of fastening. Fig. 7 is a section on line 7 7 of Fig. 3.Fig. 8 is a section on line 8 8 of Fig. 5. Fig. 9 is a section on line 99 of Fig. 6.

The tie l is constructed of metal having formed therein suitable groupsof vertically disposed passages 2 which are threaded so as to providegrooves 3 for a purpose to be hereinafter described. The passages arepreferably cylindrical in cross section and are longitudinally taperedthe small ends of the passages being disposed lowermost. These passageshave fitted therein the wedge keys 4 which are preferably constructed ofwood or other suit-able material which may be expanded withoutsplitting. The groups of passages 2 are arranged with respect to eachother so that two are located at each side of the base flange of therail A. The fastening spikes 6 are of usual well known construction,being driven downwardly into the expansible keys 4. These spikes areprovided with the head portions 7 which are adapted to engage the basefiange of the rail, as shown. On the effective driving action of thespikes into the keys 4, the keys will be swelled or expanded, hence theprovision of the grooves 3 in the key-receiving opening. The groovesserve to allow eX- pansion of the keys and thereby prevent theirsplitting when the spikes are driven thereinto.

The tie is provided with horizontally disposed recesses 8 and fittedtherein are the wooden cushioning blocks 9. These blocks are disposedbeneath the base flanges of the rails and serve materially in cushioningthe shock and absorbing the vibrations, incident to the travel of therolling stock. The blocks 9 are provided with fingers or eX- tensions 10which are arranged in the intervening spaces between the companion pairsof keys 4.

In the form of the invention shown in Fig. 4, the opening 11 in the tieis cylindrical in cross section and straight or of the same diameterthroughout so as to receive a correspondingly constructed key 12.

In the form of the invention shown in Fig. 5, the opening 13 isvertically disposed,

being rectangular in transverse section and l tapered longitudinallythroughout, the small end being disposed lowermost. This openingreceives the correspondingly formed key 14.

In the form of the invention shown in Fig. 6, the opening 15 isrectangular in cross section and is of the same diameter throughout.This opening receives a correspondingly formed key 16.

I claim:

The combination with a metal tie; and companion pairs of fasteningdevices including rail engaging spikes and eXpansible members receivingthe spikes and fitted in the tie; of a yieldable member mounted on theupper surface of the tie and having portions fitted in the interveningspaces between the companion fastening devices.

In testimony whereof I aftX my signature in presence of two witnesses.

BENJAMIN MCCANN.
